In addition to the other comments here, I am fighting illegal building taking place on a property border between my back yard and an idiot neighbor. To collect evidence for use by my county government to enforce the laws that pertain to this activity, I must stand around recording with a movie camera, and can only do that when I see or hear activity taking place.
If I had the ability to view the clips with a computer, I could also record the clips onto a USB thumb drive and just hand a collection of clips to the county officials. This would eliminate the waste of my time to upload clips to YouTube ad the waste of time for county folks to find my stuff to watch it. They could just insert my drive into their computer to see the clips.
Of all of the performance issues being discussed on this forum, THIS is the most important to me.
